Unilateral congenital cataracts present multiple barriers in the development of vision and stereoacuity despite the improved visual optics that early surgery, contact lenses and intraocular lenses (IOL) have provided. With better understanding of the latent period (the timeframe in which the abnormal event has no long-term effect on visual development in the deprived eye) and the critical periods (the age range during which developing brains can be altered in a profound and permanent way by abnormal experience) for stereoacuity and amblyopia we can focus our treatment methods to not only improve vision but also develop binocularity. Fifty years ago, it was believed that it was almost impossible for an eye with a unilateral congenital cataract to achieve good visual acuity. Twenty-five years ago, we believed that it was almost impossible for an eye with a unilateral cataract to achieve stereoacuity. It is time to expand our belief that the best that we can do with the eye in unilateral congenital cataract is to create a spare.

Childhood cataract is a complex condition requiring longitudinal care, including early diagnosis, timely referral to a specialist, early surgical intervention, and dedicated postoperative care. Adherence to refractive correction and amblyopia therapy are critical for visual rehabilitation, even months to years after the cataract is removed. We review the impact of the social determinants of health on each step in the visual rehabilitation pathway for children with congenital and infantile cataracts. Children from socioeconomically marginalized backgrounds are more likely to experience delays in access to care and utilization of surgical services. They are also less likely to adhere to amblyopia therapy, with corresponding decrements in visual outcomes. Additional sociocultural factors, including parental stress, self-efficacy, and health literacy, pose barriers for these children. Standardizing clinical roles, improving health communication, managing parental stress, and implementing systemic policy changes may alleviate socioeconomic disparities in outcomes for children with cataracts.

Glaucoma Following Cataract Surgery (GFCS) remains a menace, so parents must be counseled prior to cataract removal in children. Age less than 7 months at the time of surgery increases this risk, and IOL placement has no effect. To lower IOP in GFCS, start with drops and before you escalate to surgery, consider phospholine iodide. Then, proceed cautiously with angle surgery and shunts, mixing in cycloablative procedures where appropriate in your hands. With patient-centered models for access, follow-up & adherence to treatment, GFCS can be controlled. Partnering with our certified orthoptist colleagues, we can achieve excellent results for the "whole patient" spanning cataracts, glaucoma, strabismus, and amblyopia.

Background: Reddit is particularly popular due to its anonymity and discussion forum-type format. As an increasing number of patients seek medical advice on social media online, understanding patients' activity regarding strabismus on Reddit will help assess their concerns and guide patient education.

Methods: A cross-sectional study of Reddit posts (www.reddit.com/r/strabismus/) was conducted from July 2021 to July 2022. Posts were sorted by date, type, content, emotional tone, and users' sex and age (when available).

Results: A total of 709 posts were analyzed. Of the 164 (23%) posts in which users identified sex, 85 (52%) were female. The average age of patients to whom the post regarded was 23.7 ± 11.4 years (range 1-60 years). The most common content was surgical treatment (453, 63.9%), non-surgical treatment (263, 37%), seeking a diagnosis of their condition (190, 26.8%), and sharing personal journeys (136, 19.2%). Of the 289 (41%) posts that conveyed a clear emotional tone, the most common were anxiety (48, 18.3%), happiness (31, 11.8%), insecurity (24, 9.2%), frustration (22, 8.4%), and excitement (22, 8.4%). "Anxiety" posts had a significantly greater association with pre-surgery concerns whereas "happy" posts had a significantly greater association with post-operative updates (p = .003).

Conclusions: Patients with strabismus who post on Reddit tend to be young adults interested in surgical treatment options. Although the pre-operative tone was anxiety, post-operative posts tended to be happy.

The year 2020 has been greatly anticipated by the entire ophthalmic community. This year's Scobee lecture will be a photographic look at our past with the orthoptists and pediatric ophthalmologists we have learned from, taught, and worked with. A sobering snapshot of our present will reveal a world with extreme medical access inequality. This creates a need for an inexpensive screening device for amblyogenic anisometropia. A technique for such a fast and inexpensive screening device will be shown using first retinoscopy; and then compare the effectiveness of the direct Heine streak ophthalmoscope, a common ophthalmic instrument, will be shown to be effective in screening for ≥1 diopter of spherical anisometropia. The challenges of the present hint at an optimistic future for orthoptists, expanding their role as physician extenders to help ease the medical access inequalities in the world. Finally, I introduce the patron saint of the blind and those with vision impairment.
